| 摘 要： | 兰新高速铁路经过的大风区自然条件恶劣,大风强劲、频繁,严重危害铁路运营的安全。鉴于现有的桥梁防风技术远不能满足高速铁路的要求,针对兰新高速铁路大风特征、高标准铁路的要求,对桥梁挡风结构挡风板进行设计研究。通过理论研究、数值模拟分析及风洞试验等方法,确定挡风板的合理开孔率、波高及板厚等技术参数,设计出适用于高速铁路桥梁挡风结构的挡风板。本项设计达到了本线桥梁防风技术的预期效果。

| Abstract: | Lanzhou- Urumqi high speed railway traverses through area with strong and frequent wind,which endangers the normal railway operation. In view of failure of the existing wind resistance technology to meet the requirements of high-speed railway,this paper studies and designs the bridge wind shield based on the features and requirements of high-speed railway. Reasonable hole rate,wave height and thickness of bridge wind shield are defined by means of theoretical research,numerical simulation analysis and wind tunnel test. The structure of bridge wind shield applying to high-speed railway is designed. This design meets the requirements of the line |
